Sparse joint representation for massive MIMO satellite uplink and downlink based on dictionary learning

We address the challenge of jointly representing uplink (UL) and downlink(DL) channels for a massive multiple-input multiple-output satellite system.We employ dictionary learning for sparse representation with the goal of mini-mizing the number of UL/DL pilots and improving accuracy. Additionally, b...
